Yes, use the key slip as described, only slightly depress the keys, not too
much, about 1/3 of travel. And be sure to have sustain pedal on.

 

The newer high definition systems don't require the keys to be depressed.
Reach back in a push on of the plungers down. If it is spring loaded it is
an older system and the keys need depressed. If it is not spring loaded it
is a new system and it is SUPPOSED to be adjusted just to the bottom of the
keys so the key should not need depressed. 

 

To adjust pedal solenoid, adjust lift first. Pull plunger down and the
bicords should not quite clear the strings. You want just barely enough
lift. Then adjust the stop, which is on top of the solenoid, so that there
is virtually no lost motion. You want very little solenoid travel to
minimize noise, both in activation and the whump that occurs when the
dampers return to the strings. Software also needs set to adjust the strike
force ( the initial force to lift the dampers) and the hold force ( the
force required to hold the dampers after they are lifted). If the complaint
is that the dampers are not sustaining during Pianodisc operation, these
parameters may need adjusted. I'll be happy to walk you through if you need
help.

Not quite... you can slide the action so the front of the keyframe is even
with the front edge of the keybed. Then press the sustain pedal, AND use the
keyslip to depress ALL 88 keys while you push the action back to its proper,
final position. 

 

To use the keyslip to do that, rest it on the fronts of the sharps so the
lower corner edge is on the naturals and the back side is on the upper front
"corners" of the sharps. Then press down, hold, slide the action in.

List,
I need to do some damper action regulating on a Samick grand with Piano Disc
system .
Am I correct in the fact that the action needs to be lifted up to clear
things when being slid back in?
